DRIVE BELT INSTALLATION
NOTICE
Always clean the drive belt using a mixture of warm,
soapy water. Allow to air dry. When installing the belt,
verify POLARIS or the part number can be read from
the outside of the snowmobile.
1. Verify the driven clutch sheaves are open. If they are
not, install the L-wrench and open the sheaves.
2. Drop the drive belt over the drive clutch and pull back
the slack. The belt cord line should be flush with, or
slightly above, the outer circumference of the driven
clutch sheaves.
3. Hold the belt down between the sheaves and roll the
bottom portion over the outer clutch sheave. Work the
belt to the outer edge of the sheave.
4. Turn the L-wrench counterclockwise to tighten the
sheaves. Work the belt around the clutches as you
remove the L-wrench. Doing so will set the belt in “low
gear”.
5. Reinstall the wrench
q
to the wrench bracket to
secure the fender to the console.
6. Reinstall the left side panel.
7. When installing a new belt, follow the belt break-in
procedures.
